The lack of access to functional foods and the constant consumption of low-nutritious foods have increased the prevalence of Non-Communicable Diseases (NCDs), affecting young and middle-aged people. The use of wild species with a high content of active components could mitigate these diseases. Rubus ellipticus Sm. is one of these species with great nutritional potential that is not being exploited. This research aims to evaluate the extract of Rubus ellipticus Sm., its microencapsulation through spray drying and its implementation in gummies. The fruits collected in the province of Imbabura were analyzed to determine their physicochemical properties. Extraction of the active compound was performed with ethanol followed by microencapsulation. The polyphenols present in the sample were evaluated using the Folin-Ciocalteu method and Infrared Spectroscopy, and the antioxidant capacity was eliminated with the in vitro 2,2-diphenyl-1-picrylhydrazyl (DPPH) method. The extract was microencapsulated with maltodextrin in a 20:80 ratio, showing an efficiency of 85.76 percent, obtaining 124.754 mg EAG and 372.01 µmol Trolox per 100g, with 64.64 percent inhibition of the DPPH radical. . In the gummies, the antioxidant activity had a minor decline while maintaining the percentage of inhibition of the DPPH radical, and its sensory analysis showed high acceptability despite the detection of changes in the formulation. These results indicate that Rubus ellipticus fruits have great potential as a source of antioxidants, suggesting their implementation as an alternative to enrich products in the food industry.
